[0002] A lidar scanner is a physical performance test instrument used in the field of surveying and mapping science and technology. It is a radar system that emits laser beams to detect the position, speed, and other characteristic quantities of targets. Its working principle is to emit detection signals to targets and use laser beams to sense surrounding objects. By comparing the received signals reflected from the targets with the emitted signals and performing appropriate processing, relevant information about the targets can be obtained, such as parameters like target distance, azimuth, height, speed, attitude, and even shape. Thus, the targets can be detected, tracked, and identified, and the positions and morphologies of surrounding objects are reflected in the form of point cloud data. It is widely used in aspects such as resource exploration, urban planning, agricultural development, water conservancy projects, land use, environmental monitoring, transportation and communication, earthquake prevention and disaster reduction, and national key construction projects, providing extremely important original data for the national economy, social development, and scientific research.

[0003] To facilitate scanning operations, in the prior art, a handheld lidar scanner is used, and the lidar scanner and the maintenance terminal are integrally held and moved through a back clamp and a handle. However, in the handheld devices of the prior art, the lidar setting part is detachably arranged with the back clamp and the handle, with a large volume, inconvenient to carry, and poor stability.

[0004] On the other hand, in the prior art, in order to reserve sufficient installation space for the lidar and provide space for the limiting of the terminal device and the handholding of the operator, it also causes the handheld lidar scanner device to have a large volume, inconvenient to carry and operate, resulting in low utilization rate.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0037] The solution of the present application provides a back-clamp type lidar scanner, such as Figures 1 to 8As shown in the figure, it includes a housing and a clamping mechanism provided on the housing. The housing includes a radar installation part 3 and a placement part for receiving the workpiece to be clamped. Part of the radar is located within the radar installation part 3. The clamping mechanism includes an adjustment component that moves horizontally along the placement part to adjust the horizontal width of the placement part.

[0038] In the solution of this application, the lidar 10 uses a high-frequency and high-precision lidar to achieve high-frequency and high-precision measurement. And part of the lidar 10 is installed internally, with the light-emitting area exposed, which is beneficial to improving the assembly stability of the lidar 10 and reducing the overall volume of the device. At the same time, integrating the lidar 10, the clamping mechanism, and the placement part into the housing results in a high degree of device integration, a compact structure, and a small appearance size, facilitating technicians to carry and operate. The movement of the adjustment component changes the area of the placement part, which is conducive to the device placing and clamping terminal devices of different sizes, further enhancing the practicability and compatibility of the device in this solution.

[0039] In one embodiment, an avoidance cavity is provided inside the housing, and at least part of the lidar 10 and the adjustment component are located within the avoidance cavity.

[0040] Preferably, the housing includes a front shell 1 and a rear shell 2. The radar installation part 3 is arranged on the front shell 1, and the front shell 1 and the rear shell 2 are covered to form an avoidance cavity.

[0041] Further, the radar installation part 3 is provided with an installation opening adapted to the lidar 10. The bottom of the lidar 10 is located within the installation opening and is connected by a wire to a radar charging board 8. The lidar 10 is fixed to the front shell 1, and the radar charging board 8 is fixed to the rear shell 2.

[0042] By setting the front shell 1 and the rear shell 2 to be covered to form an avoidance cavity inside, on the one hand, it is beneficial to reduce the overall weight and the holding burden, and on the other hand, it is convenient to arrange and connect components inside the housing, improve the utilization rate of the internal space of the device, and improve the structural compactness of each component, thus facilitating reducing the appearance size and being convenient to carry and use.

[0043] In one embodiment, the placement part includes a placement board 21, and the adjustment component includes clamping plates 4 respectively arranged on both sides of the placement board 21, and the clamping plates 4 are perpendicular to the placement board 21.

[0044] Further, the adjustment component includes a torsion spring 6 located within the avoidance cavity, and a limiting plate 5 connected to the clamping plate 4. The limiting plate 5 is provided with a limiting groove 51 for carrying the torsion spring 6, and the clamping plate 4 drives the limiting plate 5 to move horizontally along the placement board 21.

[0045] Preferably, a flexible protection pad is provided on the inner side of the clamping plate 4. The flexible protection pad can be a silicone protection pad, and the surface texture is used to increase the friction force between the clamping plate and the handheld terminal during clamping, which is beneficial to improving the clamping stability, and is also beneficial to playing a mobile buffering role for the clamped device, preventing problems such as device wear or device dropping caused by too loose clamping.

[0046] Further, the clamping mechanism includes a limiting protrusion 7 provided on the inner wall of the housing. The limiting protrusion 7 abuts against one end of the torsion spring 6 close to the clamping plate 4, and the projection of the torsion spring 6 in the vertical plane falls on the placement plate 21.

[0047] As Figures 1 to 5 shown, the inner wall of the front shell 1 or the rear shell 2 bulges towards the center of the housing to form the limiting protrusion 7. In this embodiment, the clamping plate 4 is separately designed from the front shell 1 and the rear shell 2 to achieve smooth movement of the clamping plate 4. The inner wall of the front shell 1 is provided with the limiting protrusion 7, and the horizontal section of the rear shell 2 below the radar forms the placement plate 21 to abut against the clamped part. The placement part further includes a protection plate 11 corresponding to the placement plate 21. The part of the front shell 1 corresponding to the placement plate 21 forms the protection plate 11, so that the front shell 1 and the rear shell 2 are surrounded, and an avoidance cavity is formed between the placement plate 21 and the protection plate 11. When in use, the clamping plate 4 is pulled, and the limiting plate 5 connected to the clamping plate 4 moves outwards towards the avoidance cavity, driving the torsion spring 6 located in the limiting groove 51 to move simultaneously. The torsion spring 6 is compressed by the resistance of the end limiting protrusion 7. After the clamped part is placed, its side wall abuts against the side wall of the clamping plate 4 and acts together with the limited torsion spring 6 to prevent the clamping plate 4 from retracting.

[0048] And it should be noted that, as Figures 1 to 8 shown, the clamping mechanism further includes a positioning plate cooperating with the clamping plate 4. The positioning plate and the clamping plate 4 are respectively arranged on both sides of the housing. When clamping, the clamping plate 4 is pulled, and the positioning plate and the clamping plate 4 cooperate to form a limit on the left and right sides of the clamped part. There is no need to additionally set a group of limiting plates 5 and torsion springs 6 connected to the positioning plate. The positioning plate always remains stationary, saving internal space, reducing the processing difficulty and the assembly difficulty, and at the same time being beneficial to ensuring the clamping stability.

[0049] In addition, as Figure 1 shown, a handle position 41 is provided on the clamping plate 4, and the handle position 41 is provided with patterns to increase the friction force, facilitating the outward pulling of the clamping plate 4 and preventing the hand from slipping due to too small friction force.

[0050] Preferably, a plurality of torsion springs 6 are provided, and the plurality of torsion springs 6 are evenly distributed. This is beneficial to improving the overall force stability and strengthening the clamping stability of the handheld terminal.

[0051] In one embodiment, three limiting grooves 51 are provided and three torsion springs 6 are correspondingly provided. The limiting plate 5 has the same width as the clamping plate 4, and the three limiting grooves are of the same size and are evenly distributed along the width direction of the limiting plate 5. The three torsion springs have the same specifications and dimensions. One side of each torsion spring is located in the limiting groove 51, and the other side abuts against the inner wall of the housing, so that when the clamping plate is pulled, the limiting protrusion 7 forms a resistance against the torsion spring 6.

[0052] In addition, a charging port 9 is provided at the bottom of the housing.

[0053] As Figure 3 , Figure 6 shown, it should be noted that, as an embodiment of the present application, the lidar 10 adopts a new generation of coaxial design, which can achieve 360° scanning and ranging, and the maximum measurement radius can reach 12 m. It is applicable to map surveying and mapping, navigation and obstacle avoidance of intelligent devices, environmental modeling, etc. The charging board is connected to the lidar 10 and an external system through a standard interface to achieve power supply, rotation control and data reception. In addition, the charging board is connected to the connection seat 11, and a charging wire 12 is led out through the charging port 9 and connected to a handheld device to supply power to the lidar. The connection seat is fixed to the inner wall of the housing.

[0054] The back clip of the solution of the present application integrates the lidar 10 and the clamping mechanism, and can clamp maintenance terminals of different size specifications through the clamping mechanism. There is no need to additionally set a handle, and the maintenance terminal can be directly held for operation. When in use, the overall size is small and the stability is good, which is beneficial to improving the measurement accuracy and the convenience of use.

[0055] And in the present application, the clamping orientation of the handheld terminal can be selected according to the actual situation. As Figures 6 to 8 shown, when it is necessary to use the lidar 10 in the same direction as the liquid crystal screen of the handheld terminal in special cases, the lidar 10 can be clamped in the same direction as the liquid crystal screen. And since there are no other components such as handles below the back clip, the liquid crystal screen will not be blocked, and the use requirements in various scenarios can be met.

[0056] What is not described in the present application can be realized by adopting or referring to the existing technology.

[0057] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments.

[0058] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
